Believing old luck has an effect on future luck is called gambler's fallacy. It's some sort of weird superstition, i.e. wrong. Wikipedia has a page for this: http://en.wikipedia.org/wiki/Gambler%27s_fallacy
Believing bad luck never happens, is there a name for that? How can we convince people that bad luck will happen naturally and should be expected? Any good internet resources for this?
What about those who believe they are born with bad luck and if luck is involved then it will always be bad for them. It seems often impossible to convince them of anything else.
